Fundamentals of Geosynthetics – Types, Functions, Selection and Performance PT 1 – Materials 
Kerry Petrasic, Gannett Fleming

This short course provides an overview of geosynthetics materials.  The course is independent of the Part 2 course offered in the PM session, but is complimentary.  The course is intended for individuals with a desire to explore the use of geosynthetic materials in design and construction applications, and those having a need to gain a broad fundamental knowledge of the various geosynthetic types, materials and functions.  The course provides a basic definition of geosynthetics, explores the various geosynthetic material types, the polymers used in manufacturing, strengths and weaknesses of the common polymers, and the physical structure of the various types of geosynthetics.  The prominent roles of polymer type and material physical structure are emphasized in the effective selection and optimal performance of geosynthetics for a specific function.  Geosynthetic materials discussed include geotextiles, geogrids, geocell, geomembranes and geofoam.  Importance is placed upon desired function(s) in the selection of geosynthetic material class and type.

Geosynthetics in Erosion and Sediment Control and Erosion-Resistant Hydraulic Structures
Joel Sprague, TRI Environmental; Nathalia Castro, Solmax

Geosynthetic-enhanced erosion and sediment control systems are now used routinely in temporary construction site applications, as well as, in steep slope stabilization and shoreline and coastal erosion protection. On the construction site, geosynthetic-enhanced rolled erosion control products (RECPs) and sediment retention devices (SRDs) have become essential to pollution prevention plans. In permanent applications, geosynthetic solutions now include specially designed geotextile filters beneath hard armor systems, and deploying advanced erosion protection technologies such as anchored geotextiles, geocellular containment systems, fabric-formed concrete revetments, and sand-filled geosynthetic mattresses, tubes, and other containers. This short course will provide and detailed look at all these emerging technologies and how they are being used to cost-effectively protect against erosion from rainfall, runoff, stream flow, and shoreline wave action.

Landslide Remediation with Geosynthetics-Evaluation Methods and Construction Techniques
Stephan Gale and Nathan Lichty, Gale-Tec Engineering

Increased rainfall amounts and intensities, along with prolonged wet periods have created slope instabilities along our roadway embankments and rivers/streams channel sideslopes. The exact causes of these vary, but the threat to public safety is a constant. This short course will assess the causes, discuss the evaluation of alternate solutions and present construction case histories which include a wide range of resilient landslide remediation solutions for each of the unique challenges presented with each project.

This course will highlight recent projects that balance geotechnical needs, hydraulics, local and federal permitting requirements, wetland impacts, special river designations, costs, unique site constraints and aesthetic goals to arrive at cost effective solutions. Through a series of case histories, we will review design and constructed solutions ranging from hard armored riprap and gabion walls to vegetation faced geosynthetic reinforced soil slopes with various erosion resistant faces  as well as shallow soil anchors or grouted hollow bar reinforcement installed on a reconstructed slope face.

Marketing in the Geosynthetics Industry
Sam Allen, TRI Environmental; Tamara Tuttle, Atlas International Consulting

While the global geosynthetics industry is relatively small (an international geosynthetics conference may attract at most 2500 people), it is uniquely intense with many companies providing services ranging from geosynthetic products, geosynthetic installations, and expertise related to geosynthetic design, application, and testing. Most professionals in the geosynthetics industry have achieved much of their expertise during their professional career with a fortunate few having had geosynthetic -related curriculum in school.

The geosynthetic industry involves many with disparate educations ranging from classic geotechnical, civil and environmental engineering to technical backgrounds in chemistry, polymer engineering and materials science. Still others in our industry are solely trained based on multi-year experience with geosynthetic manufacturing, handling, installation, and testing.

From a marketing and sales communication perspective, this dynamic industry poses an especially challenging environment to establish meaningful communication with our collective customers. Indeed, navigating the multiple geosynthetic-related associations and non-profits, and their cultures and contributions can be daunting. Yet, these same organizations play a strategic role in standardizing and promoting geosynthetic technologies and applications – a key benefit to geosynthetic sales professionals. They stand as platforms for collective education and community held expertise as compared with company-specific messaging promoting the unique attributes of a product or service.

So, how is one to sell products or services in such a dynamic and competitive industry?

This half-day course is appropriate for business development and sales professionals working in the geosynthetics industry. It is appropriate for new hires, young starters, and seasoned professionals. Students will explore the different geosynthetic industry sales environments and how general and broad appreciation for the industry and its organizations can greatly enhance the success of sales efforts. Narratives commonly heard about geosynthetic types and features and their relative performance will be explored and evaluated in a non-competitive, safe environment. Healthy and positive sales techniques will be discussed and rehearsed.  Students will gain an intense and expanded appreciation for the uniqueness and greatness of the global geosynthetics industry and its opportunities.

AASHTO 2020 Design Methods of Geosynthetic-Reinforced Walls
Dov Leshchinsky, University of Delaware and ADAMA Engineering; Daniel Alzamora, FHWA Resource Center

This short course provides an overview of the AASHTO 2020 methods for the design of geosynthetic-reinforced walls. Discussed are the Stiffness Method, the Limit Equilibrium Method, and the Simplified Method. While the main focus will be on internal stability, aspects such as complex geometries, surcharge loads, external stability and seismic design will be discussed as well. Instructive examples will be used to demonstrate the fine points of each method while showing the differences in the design outcomes. To expand the number of comparative cases, both programs MSEW+ and ReSSA+ will be used.

Construction on Soft Soil using Geosynthetics
Lilma Schimmel, AECOM and Alex Potter-Weight, Menard USA

This course will on focus the use of geosynthetics to address the challenges of construction on poor soil conditions. Commonly used and innovative techniques will be discussed at an introductory level, including Geosynthetic Encased Columns (GECs), Prefabricated Vertical Drains (PVDs), High Strength Basal Reinforcement and Load Transfer Platforms. Technical information about specification parameters and design using geosynthetics will also be introduced.

Designing for a Zero-Leak Containment Facility
Abigail Gilson MS, PE, TRI Environmental and Jeff Blum, Weaver Consultants Group

The old adage that “all liners leak” does not have to be a foregone conclusion. All leaks in lining systems have a direct cause including accidents, installation issues, poor craftsmanship, inadequate material testing, and poor design decisions. A holistic approach to leakage is taken in this course to address both short-term and long-term sources of leakage. Using state-of-the-art Electrical Leak Location (ELL) technologies, leaks can be remedied before a containment facility is put into service. Employing best practices for Construction Quality Assurance (CQA) can eliminate leaks that develop over time due to poor installation practices. In short, the reduction or even elimination of leakage starts in the design phase with good project specifications. This course provides Engineers with the tools they need to write better specifications aimed at reducing or even eliminating leakage, as well as providing practical tools for designing for a target leakage rate.

Course Outline:

• The physics of ELL testing methods and how to maximize method effectiveness (Gilson-Beck)
• Fundamentals of Electrical Leak Location
• Available Methods
• Bare Geomembrane methods

Geosynthetic Reinforced Embankments on Soft Foundations
Bob Holtz, PhD, PE, D.GE, Dist. M. ASCE, University of Washington

The design and construction of embankments on very soft foundations is one of most challenging geotechnical problems.  Without some type of foundation soil improvement, failures are common especially on very soft sites.  Soil reinforcement with geosynthetics is often the only economical solution, and some projects could not be constructed without geosynthetics.  The lecture begins with a brief overview of conventional treatments for soft ground construction.  Early case histories, mostly failures, are described that provided valuable lessons and concepts that we use today for design and construction.  Analysis and design procedures are then outlined, along with the selection of the required properties for the geosynthetics and embankment soils.  Sample specifications, cost considerations, as well as inspection and instrumentation are also described.  Because proper construction is so critically important for success of these projects, a detailed discussion of construction procedures completes the course.  Detailed lecture notes and copies of the course slides will be available.

Geosynthetic Stabilization of Granular Layers in Paved Roads
Erol Tutumluer, PhD, University of Illinois at Urbana-Champaign, Jorge Zornberg, PhD, PE, The University of Texas at Austin

Geosynthetic stabilization is often associated with a paved road when an aggregate base/subbase is constructed over a subgrade having CBR ranging from 3 to 8 (FHWA, 2008). The main benefits of unbound aggregate layer stabilization include (1) decreasing time-dependent rutting by providing an increased modulus of unbound aggregates at the time of construction and added confinement from compaction-induced geosynthetic tension and (2) minimizing degradation of the modulus of unbound aggregates over time by proper control of lateral displacements in unbound aggregates and maintaining initial confinement of unbound aggregates. The identified mechanism is the development of lateral restraint through tension and shear transfer to minimize the lateral displacement of unbound aggregates. Both friction and interlocking between aggregates and geosynthetics contribute to the base stabilization. Modern design procedures are needed for establishing more common use of geosynthetics for base stabilization within the framework of a mechanistic-empirical pavement design approach. This workshop is intended to present, review an discuss the latest developments in the quantification of aggregate layer stiffness characteristics of the geosynthetic-aggregate geocomposite, aka, the mechanically stabilized layer. Through presentations and discussion, a path to development of modern design procedures will be presented.

Learn The Concept of The Dewatering Tube System Through Experience
Ike Chen and Zoe Lin, ACE Geosynthetics, Marco A. Sánchez, Commercial Director, ML Ingenieria; Seva Iwinski Bray and Eddie Snell, Applied Polymer Systems; Carlos Moreno, Pavco Wavin Geosynthetics (Columbia)

Geotextile tube is proven to be a cost-effective solution for some hydraulic and civil engineering applications. In addition to this, geotextile tube is also recognized as a good approach for some dewatering needs. And there are many factors that can affect the dewatering performance of a geotextile tube; besides the characteristics of slurry, the selection of geotextile, and the selection of polymer and its dosing ratio are also key factors. This workshop will focus on understanding how the selection of geotextile and polymer’s dosing ratio affect the dewatering performance of geotextile tube by practical experiment.This is a hands-on dewatering workshop

30 Years of Lessons Learned on Geomembrane Installation Quality 
Glen W Toepfer, CQA Solutions, Ltd.

Geomembranes are a vital and primary barrier to prevent of environmental contamination.  Given the critical role of geosynthetics in environmental containment systems, correctly executing field construction is imperative to successful projects.  So where do you go to learn correct construction processes, quality control, quality assurance and common pitfalls?  The answer for most is you don’t.  As a word of mouth trade there has been a significant lack of formalization of field processes.

This workshop is here to share lessons learned from over 30-years of field CQA throughout the United States.  We will share lessons learned from all project phases – from conception through operations, as each phase is critical to long-term performance of the geomembrane barrier.  Issues that should have been caught are often missed or overlooked, leading to potential catastrophic long-term impacts on the ability of a geomembrane to meet its designed/required containment objectives.  Lack of knowledge is a key reason things get missed during construction.

Attendees will examine physical samples from the field, view numerous photographs and/or video while given a detailed discussion of key visual indicators, consequences, preventative measures, and proper resolution of issues.  Discussions will also include proven best practices that are often overlooked or not used.

Topics will include: tips for identifying potentially suspect/inferior materials before shipment to site; discussion of common and not so common pitfalls in geomembrane containment system installations which compromise quality objectives; and the often-misunderstood limitations of new/developing technologies.

Two hours may not make you an expert of Geosynthetics but it can revolutionize how your field construction is executed to ensure better projects and a better environment.

Session Chair: Robert A. Gladstone, P.E., Executive Director, Association for Mechanically Stabilized Earth (AMSE)

Mechanically stabilized earth (MSE) structures depend on frictional interaction between reinforcements and reinforced backfill for their internal stability.  Therefore, the physical, mechanical and electrochemical properties of the chosen backfill are critical to designing safe structures which will provide a long service life.  At sites having weak foundation soils, backfill unit weight may negatively affect external stability.  For any project, if naturally occurring backfill satisfying both internal and external stability requirements is not available on site or from an economical haul distance, there are alternative backfill materials which may be considered.

Alternative backfills for MSE structures are typically manmade or reprocessed/recycled from manmade materials.  Examples of such materials include low density cellular concrete, foamed glass aggregate, vitrified shale, clay and slate, and recycled concrete.  This Special Session will educate attendees about these four alternative MSE backfills, including their physical, mechanical and electrochemical properties, their cost implications, and any special considerations when used to construct MSE structures.  Example MSE projects may be mentioned in this session but, for case history presentations, conference attendees should plan to attend the companion Special Session, MSE Structure Case Histories Using Alternative Backfill Materials.

Robert M. Koerner Award and Lecture | A Conversation with JP Giroud
From Zero Leak at end of Geomembrane Installation to Zero Leakage in Service
J.P. Giroud, ECP, PhD., Past President International Geosynthetics Society

Dr. Giroud will join us live from France with a lecture followed by an interview style q&a session. Attendees are invited to submit questions for potential inclusion in the q&a. Start thinking now about what questions you would ask this geo-legend!

From Zero Leak at end of Geomembrane Installation to Zero Leakage in Service
Zero leak at end of geomembrane installation may be nearly achieved when electrical leak location surveys are performed by first-class operators working under ideal conditions; and nearly zero leakage in service is a legitimate goal under ideal conditions. However, there are still too many instances of failures of geomembrane-lined containment facilities, often as a consequence of improper design, and generally resulting in significant leakage. The lecture will present mechanisms of failure, with actual examples whenever possible, and will recommend design measures to avoid each specific failure mechanism. While nearly zero leakage in service cannot be guaranteed and, generally, is not achieved, the rational approach presented in the lecture consists in reducing the leakage rate to a level where the predicted consequences of leakage are acceptable considering the nature of the geomembrane-lined containment facility and its environment. The conclusion of the lecture will point out that the use of geomembranes in containment facilities is essential for the protection of the environment, not only by preventing migration of contaminants into the ground but also by reducing water waste. Indeed, saving water will be a major economic and environmental challenge for the coming decades

Numerous MSE structures have been built using manmade or reprocessed/recycled materials such as low density cellular concrete, foamed glass aggregate, vitrified shale, clay and slate, and some industrial waste products. These materials are often selected because of their lower unit weights compared to naturally occurring backfills.  Reduced unit weight can help address design challenges caused by settlement-prone or otherwise poor foundation soils, but the selected backfill must also have the properties necessary for MSE structure stability and long term performance.  Presenters in this Special Session will provide case histories of geosynthetic-reinforced (and one or two steel-reinforced) MSE structures constructed with alternative backfills, including referencing project conditions driving backfill selection and any special construction practices related to use of that backfill.  Conference attendees should plan to attend the companion Special Session, Alternative Backfill Materials Applicable to MSE Structures, for more detailed information on several alternative MSE backfills.

This Panel Discussion will assemble  industry leaders to discuss the importance of writing a good geomembrane specification and not using an old specification that may or may not be for the type of geomembrane intended for the current project. In particular, the panelists will discuss the most important parameters of a geomembrane specification for a particular application, such as, functionality, longevity, and constructability. Some of the important parameters to consider when preparing a specification may include: chemical resistance, ability to accommodate differential settlement, dimensional stability to control wrinkles, ability to factory fabricate large panels to reduce field time and exposure, and seam strengths but properties should be keyed to the application of the geomembrane. For example, if there are concerns about subgrade compaction, specifying a material with higher multiaxial elongation properties may be desirable.  It is also important that engineers understand that most material types can have very different properties and it is important that designers select an appropriate geomembrane to meet project requirements.  This will help avoid confusion or blended specifications. Finally, the importance of specifying relevant and consistent properties, e.g., long-term durability in terms of plasticizer retention instead of OIT values for a PVC geomembrane. Afterwards, the panelists will answer attendees questions about writing a good geomembrane specification.

Moderator: Timothy Stark, PhD, University of Illinois at Urbana-Champaign
This Panel Discussion will assemble four (4) industry leaders to discuss the advantages and disadvantages of giving owners and operators an Operation and Maintenance (O&M) manual for their installed geosynthetics. The panel discussion will commence with a description and discussion of the first FGI O&M Manual for water reservoirs and the checklist included to facilitate periodic inspection. The second FGI O&M Manual for a floating cover system over water reservoirs is under preparation and will be outlined. The FGI thinks an O&M plan should be standard practice for each project to obtain longer service life and meeting project expectations. The panelists will discuss the many significant problems that can be avoided by periodic inspections and minor maintenance, e.g., removal of vegetation on or under the geosynthetics and careful use of equipment around the geosynthetics, such as lawnmowers. As an exposed liner ages, sample coupons of geomembranes can also be removed for testing purposes to help owners determine the remaining life of the geomembrane.  Afterwards, the panelists will answer attendees questions about O&M activities and discuss the benefits of including sample coupons that can be removed for testing to assist owners with determining remaining service of the geomembrane.
